A hybrid platform is proposed for optical processing with capabilities beyond the standard use for spatial filter coefficients. Time domain operations are explored utilizing electro-optical components to generate and steer an optical beam across the digital micro-mirror device (DMD). An input signal in the form of a collimated optical beam is scanned through an imaging optic across the DMD to achieve 1-D operations. Coefficient “bit depth” is determined by the mirror pattern in the local spot zone giving a ratio of ‘on’ state to ‘off’ state area. The reflected signal returns along the original path through the imaging lens and is read by a receiver. Design feasibility is presented along with initial experimental results.
We describe the benefits to camera system SWaP-C associated with the use of aspheric molded glasses and optical
polymers in the design and manufacture of optical components and elements. Both camera objectives and display
eyepieces, typical for night vision man-portable EO/IR systems, are explored. We discuss optical trade-offs, system
performance, and cost reductions associated with this approach in both visible and non-visible wavebands, specifically
NIR and LWIR. Example optical models are presented, studied, and traded using this approach.
